After changing lightbulb red solid power light and flashing lamp indicator. We've changed the lamp with 3 different ones.

That is a problem with the lamp. Replace it with a known good one.

Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

A continuous flashing red light with the word LAMP on it would definitely mean you're going to need to spend a few bucks on a new lamp....or for a few more, upgrade to a TV from this century that doesn't require lamp changes :)

First check your bulb properly matched with your projector. After changing the lamp reset the lamp hour (counting from 0hrs). Adjust the osd transparency.

If u set the lamp properly then It may cause the lamp circuit need repair.

Have you got yellow lamp indication before change the lamp? If occur then you have been late to change it. If you used it up to 2500hrs. then this problem may arise. Check those first if everything ok then may be the circuit have some problem, go to the nearest sharp authorize service center or visit website.

Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself

Hello, unfortunately the NEC MT1060 - MT1070 series projectors have EEPROM chips built into the lamp housing which counts the hours that the lamp has been used for so the only way to reset the hours is to change the lamp for a new one, if your old lamp has only had the reflector replaced then it will make no differance because the chip tells the projector weather or not to power up depending on the hours its counted, i have not yet found a way to reset the chips even by reprogramming them, i'm afraid the only solution is to replace the lamp with an official NEC unit, but this was obviously their intention, just as an added note, a solid red lamp indicator light means that the lamp has expired, if its flashing red this means its nearing the end of its life, if the status indicator light is flashing then there could be another issue, by counting the flashes you can reffer to the manual in the troubleshooting section to diagnose the fault, I know this is very late, but anyone else reading this may find it helpfull.

check the covers you removed to change lamp they have safty switches if the cover is no on correctly it will not work

I would agree. Balast needs to be changed

contact your dealer for service flashfor this symptom.(light tunnel)
